Be it known that I, BERNHARD PETERSON, a citizen of the United States,residing at Cranston, in the county of Providence and State of RhodeIsland, have invented a new and useful Improvement in Bracelets, ofwhich the following is a specification.

This invention has reference to an improve ment in bracelets, and moreparticularly to 1an improvement in concealed hinges for braceets.

The object of my invention is to mprove the construction of a concealedhinge for bracelets, thereby providing a bracelet with a strong anddurable concealed hinge that is not liable to wear loose and is simplein construction, whereby the cost of manufacturing the same is reduced.

My invention consists in the peculiar and novel construction of aconcealed hinge for bracelets, said hinge having details ofconstruction, as will be more fully set forth hereinafter and claimed.

Figure 1 is a side view of a two-part bracelet provided with my improvedconcealed hinge and showing the bracelet in the closed position in fulllines and in the open position in broken lines. Fig. 2 is an enlargeddetail sectional view through the shell of the hinge end of the braceletlooking at the outside face of the hinge, with the hinge in the closedposition. Fig. 3 is an enlarged detail sectional view similar to Fig. 2looking at the inner face of the hinge, with the hinge n the closedposition. Fig. 4 is an enlarged detail sectional view taken on line 4 4of Fig. 2, through the hinge members and adjacent ends of the braceletand showing the hinge in the closed position in full lines and in theopen position in broken lines. Fig. 5 is an enlarged detail side view ofthe interlocking pintle-block removed from the hinge, and Fig. 6 is anenlarged detail sectional view taken centrally through one of the hingemembers.

In the drawings, a indicates a semi-oval half, b a correspondingsemi-oval half, and c the concealed hinge of the bracelet. The semi-ovalhalves a and b are formed from a tube which is oval in cross-section.The half a has the open end 7 for the hinge and the end 9 The half 6 hasthe open end 8 for the hinge and the end 10. The ends 7 and 8 and theends 9 and 10 coincide when the bracelet is closed. The ends 9 and 10may be provided with any one of the well-known forms of catches adaptedto hold the ends together when the bracelet is closed.

My improved concealed hinge 0 consists of two identically-constructedhinge members (1 d and an interlocking pintle-block e. The members d dare shaped to fit in the open ends 7 and 8 of the bracelet and curved toconform to the contour of the ends of the bracelet, as shown in Fig. 4.Each member (1 is constructed integral to have a solid oval body portion11 extending in, from one end of which is a central slot 12 the width ofthe interlocking pintle-block e and-forming two side arms 13 13, havingthe fiat ends 14 14 and the oppositely-disposed curved grooves 15 15 inthe inner faces of the arms 13 13. The flat ends 14 14 of each hingemember 61 abut when the hinge is closed, and the curved grooves 15 15extend in from the outer face of the arms adjacent the base of the armsto the ends 14 14 at a point adjacent the inner face of the arms and arein the form of an arc, the center of Which is struck on the center onwhich the hinge turns. The interlocking pintle-block 6 has the solidbody 16, the thickness of which coincides with the Width of the slots 1212 in the members cl d, the curved outer edge 17 shaped to conform withthe ends 7 and 8 of the bracelet, the end stopfingers 18 18, adapted toengage with the shell of the bracelet and limit the opening movement ofthe hinge, and the oppositelydisposed curved side webs 19 19 in the formof an arc the center of which is struck on the center on which the hingeturns. The webs 19 19 on the interlocking pintle-block e are adapted toit in and have a circular reciprocating movement in the grooves 15 15 inthe inner faces of the arms 13 13.

The members of the hinge are assembled by entering the ends of the webs19 19 on the interlocking pintle-block 6 into the ends of IOO ally locksthe members together, as shown in Fig. 2. The members of the hinge arenow inserted in the open ends 7 and 8 of the bracelet in a position forthe abutting ends 14 14; of the hinge members d d, and the center onwhich the hinge turns to coincide with the juncture of the ends 7 and 8when the brace let is closed. The body portions 11 11 of the hingemembers (i d are now secured in the ends 7 and 8 of the bracelet bysolder or other means. The opening movement of the hinge and bracelet islimited by the stopdingers 1.8

18 on the interlocking pintle-block e engaging'with the ends 7 and 8 ofthe bracelet, as shown in broken lines in Fig. 4. These stopfingers alsoprevent the members of the hinge from separating when secured in thebracelet. It is evident that the grooves 1.5 1.5 could be formed in thesides of the interlocking pintleblock 0 and that the webs 19 19 could beformed on the inner faces of the arms 13 13 without materially affectingthe spirit of my invention.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a bracelet, a concealed hinge comprisingduplicate hinge members, each hav ing a body portion extending in fromone end of which is a central slot forming two side arms in the innerfaces of which are curved grooves in the form of an arc and aninterlocking pintle-block adapted to fit inthe slots in the hingemembers and having curved side webs in the form of an arc adapted toenter the curved grooves in the arms of the hinge members, and means forlimiting the opening movement of the hinge.

2. In a bracelet, a concealed hinge CO111 prising duplicate hingemembers each having a solid body portion extending in from one end ofwhich is a central slot forming two side arms on the inner faces ofwhich are curved webs in the form of an arc and an interlockingpintle-block adapted to iit in the slots in the hinge members and havingcurved side grooves adapted to receive the curved webs on the arms ofthe hinge members, and

the form of an arc, the center of which is struck on the center on whichthe hinge turns, and an interlocking pintle-block e having the solidbody 16 adapted to fit in the slots 12 12 in the hinge members (I (Z,the end stop-iingers 18 18, and the curved side Webs 19 19 in the formof an arc, the center of which is struck on the center on which thehinge turns, and adapted to fit in the grooves 15 15 in the arms of thehinge members d d, as described.

4E. The combination with the halves a and I b of a bracelet having theopen ends 7 and 8, of a concealed hinge c'composed of twoidentically-constructed members (I d, each member (I having a solid bodyportion 11 extending in from one end of which is a central slot 12forming two side arms 13 13 having the ends 14 14 and the curved grooves15 15 in the inner faces of the arms 13 13 in the form of an arc, thecenter of which is struck on the center on which the hinge turns and aninterlocking pintle-block 0 having the solid body 16 adapted to fit inthe slots 12 12 in the hinge members (1 d, the curved outer edge 17,
